I know the graph shown is only representative of the direction of the curve and is not plotted accurately, but if it were plotted, shouldn't the vertex be in quadrant IV?

Graphing Quadratic Equations

  • The graph of a quadratic function is a parabola.

  • Use the axis of symmetry to help you graph a parabola. Graph the right or left half and then reflect the graph across the axis of symmetry.

  • The maximum or minimum value of the function occurs at the vertex. Use the formula for the vertex to find the maximum or minimum.
